104, also include successively between second electrode 110 and gold-tinted unit 107：EIL (Electron Injection Layer, electricity
Sub- implanted layer) 109 and ETL (Electron Transport Layer, electron transfer layer) 108, so, injected electrons and sky
Cave can be divided into singlet state and triplet, exciton returns to base from excitation state in luminescent layer due to the compound generation exciton of coulomb interaction
Discharge photon while state to light, returning ground state from triplet excited state transition sends phosphorescence.Wherein hole injection layer 103 can help
Hole is injected into luminescent layer from anode (first electrode 102), and electron injecting layer 109 can help hole from anode (second electrode
110) it is injected into luminescent layer.Hole transmission layer 104 has the characteristics that relatively low HOMO energy levels, stronger cavity transmission ability, often
It is NPB with material, and electron transfer layer 108 has stronger electronic receipt ability, common used material PBD.Finally, shown in Fig. 1
Organic Light Emitting Diode be followed successively by since substrate 101：First electrode 102, hole injection layer 103, hole transmission layer 104,

Blue light unit and gold-tinted unit in the present embodiment luminescent layer are realized using the structure of host-guest system to light, and leads to
Often only by the use of 1%~10% phosphorescence luminescent substance be incorporated in as guest materials accounted in luminescent layer more than 90% material of main part
In compound, guest materials is responsible for lighting, and material of main part mainly transmits energy and prevents triplet state-triplet state energy from burying in oblivion.
Wherein blue light unit is to mix blue dopant, such as TBP, DSA-Ph, DB-1, DB-2 and DB-3 etc. in main body.
Gold-tinted unit in the present embodiment shares main body (co-host) using red dopant and green-doped thing and carries out energy
Amount shifts, and more red dopant mixes main body compared with the mode that green-doped thing incorporation main body is separately adulterated,
Shared body-dopant is more prone to adjust the ratio of feux rouges and green glow, and as shown in figure 1, red green dopant is incorporated into altogether together
With in main body, being thinned the thickness of luminescent layer, and then the integral thickness of device is thinned.
Fig. 2 shows gold-tinted unit excitonic motion track and luminous schematic diagram in the present embodiment, as shown in Fig. 2 gold-tinted unit
Shared main body include the first main body (host1) 1071 and the second main body (host2) 1072, the first main body 1071 and the second master
Doped with red dopant 1073 and green-doped thing 1074 in body 1072, and doping ratio is different.Therefore in doping process
In, the doping ratio of red dopant and green-doped thing in the first main body is on the contrary, red dopant exists with green-doped thing
Doping ratio in second main body is also on the contrary, the first main body and the second main body are doped with red dopant and green in the present embodiment
Color dopant, that is, energy can be transmitted to red dopant and green-doped thing, but Fig. 2 is shown in the first main body
The ratio of red dopant is more than the ratio of green-doped thing, and the ratio of the second main body Green dopant is more than red dopant
Ratio.As shown in Fig. 2 band gap (the energy between HOMO and LUMO of red dopant 1073 and green-doped thing 1074
Difference is referred to as " band gap ", for weighing whether a molecule is easily excited：Band gap is smaller, and molecule is more easily excited) value is bright
It is aobvious to be less than the first main body 1071, the band gap value of the second main body 1072, to transfer energy to dopant.It is shown in Figure 1
And the structure of articulamentum 106 is combined, the electron transfer layer in Fig. 2 close to the second main body 1072 is the electric transmission shown in Fig. 1
Layer 108, for give electric transmission to the second main body 1072, the hole transmission layer of close first main body 1071 is articulamentum in Fig. 2
In hole transmission layer 1060, for giving hole transport to the first main body 1071.
Fig. 3 shows in the present embodiment host-guest system schematic diagram in gold-tinted unit, as shown in figure 3, red dopant with it is green
Doping way of the color dopant in main body is shared is grade doping, and red dopant is mixed with green-doped thing as doping object
Enter into shared main body.And the doping ratio of red dopant and green-doped thing in main body is shared trend on the contrary, with
Exemplified by shown in Fig. 3, the side of the mass percent of red dopant close to hole transmission layer in the first main body is maximum, to
It is middle it is gradually small be 0, the side of the mass percent of green-doped thing close to electron transfer layer in the second main body is maximum,
Gradually small to centre is 0.
It should be noted that the first main body and the second main body do not divide clearly in fact in the present embodiment, both of which energy
Energy transmission occurs with red dopant and green-doped thing, structure shown in Fig. 2 is that the first main body is more partial to transmission sky
Cave, energy transmission occurs with red dopant, the second main body is more partial to transmit electronics, and energy, which occurs, with green-doped thing passes
Exemplified by passing, usual non-radiative energy transfer mode is the transfer of Forster abilities and Dexter energy transfers.
In the present embodiment, because the first main body 1071 has higher LUMO (Lowest Unoccupied
Molecular Orbital, lowest unoccupied molecular orbital) energy level, the first main body 1071 has electronic blocking function, can stop
Electrons spread is to adjacent functional layer.Second main body has relatively low HOMO (Highest Occupied Molecular
Orbital, highest occupied molecular orbital) energy level, there is hole barrier function, can stop that hole is diffused into adjacent function
Layer, so due to electronics by the first body block in luminescent layer, greatly limit the path in electronics and hole, extend electronics
The recombination time in hole so that exciton energy maximum probability it is compound in luminescent layer, the recombination rate of exciton is improved, so as to improve OLED
Luminous efficiency.
In the present embodiment, the ratio of the first main body is less than the ratio of the second main body, wherein the deviation transmission of the first main body is empty
Cave, the second main body deviation transmission electronics, can make it that electron transfer rate is suitable with hole transport speed in gold-tinted unit, ensure
Exciton is compounded among luminescent layer, the same recombination rate for improving exciton, so as to improve OLED luminous efficiency.
In the present embodiment, shared main body has high triplet T1 energy levels, can avoid it is compound after exciton to both sides
Functional layer spreads and causes exciton to be quenched, and improves luminous efficiency.The triplet T1 energy levels for wherein sharing main body depend primarily on
The triplet T1 energy levels of red dopant, red dopant, energy level scope is 2.5eV~6.0eV, wherein preferably energy level scope
In 3.0eV~5.0eV.In order to avoid the exciton after compound spreads to both sides functional layer, the triplet T1 energy level ratios of main body are shared
At least big 0.2eV of triplet T1 energy levels of red dopant or green-doped thing.
In summary, the Organic Light Emitting Diode that the present embodiment provides shares main body by red green dopant and realizes that energy turns
Move, easily adjust the luminous ratio of red green unit, so that both light intensity ratios are stable, so as to compound later with blue light unit
It is photochromic more stable, reach preferable display effect.Exciton recombination rate can be improved, avoid it is compound after function from exciton to both sides
Layer diffusion, and then reduce caused by exciton moves and be quenched, improve luminous efficiency.The integral thickness of device can not only be thinned, also
The number of organic line source can be reduced, simplifies evaporation process, the process costs of processing is reduced and reduces the evaporation stand-by period.
